    Important Safety InformationMost accidents that involve product operation, maintenance and repair are caused by failure to observebasic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardoussituations before an accident occurs. A person must be alert to potential hazards. This person should alsohave the necessary training, skills and tools to perform these functions properly.

    Improper operation, lubrication, maintenance or repair of this product can be dangerous andcould result in injury or death.Do not operate or perform any lubrication, maintenance or repair on this product, until you haveread and understood the operation, lubrication, maintenance and repair information.Safety precautions and warnings are provided in this manual and on the product. If these hazard warningsare not heeded, bodily injury or death could occur to you or to other persons.

    The hazards are identified by the Safety Alert Symbol and followed by a Signal Word such asDANGER, WARNING or CAUTION. The Safety Alert WARNING label is shown below.

    The meaning of this safety alert symbol is as follows:

    Attention! Become Alert! Your Safety is Involved.The message that appears under the warning explains the hazard and can be either written or pictoriallypresented.

    Operations that may cause product damage are identified by NOTICE labels on the product and inthis publication.

    Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard.The warnings in this publication and on the product are, therefore, not all inclusive. If a tool,procedure, work method or operating technique that is not specifically recommended by Caterpillaris used, you must satisfy yourself that it is safe for you and for others. You should also ensure thatthe product will not be damaged or be made unsafe by the operation, lubrication, maintenance orrepair procedures that you choose.The information, specifications, and illustrations in this publication are on the basis of information thatwas available at the time that the publication was written. The specifications, torques, pressures,measurements, adjustments, illustrations, and other items can change at any time. These changes canaffect the service that is given to the product. Obtain the complete and most current information before youstart any job. Caterpillar dealers have the most current information available.

    When replacement parts are required for thisproduct Caterpillar recommends using Caterpil-lar replacement parts or parts with equivalentspecifications including, but not limited to, phys-ical dimensions, type, strength and material.

    Failure to heed this warning can lead to prema-ture failures, product damage, personal injury ordeath.

    Fault detection and identification Diagnostics identify operation outside of programmed limits. Specificfault information is available even after the unit has been powered down.CANBUS only.

    Harmonic tolerance For total harmonic distortion of the generator output voltage waveform upto 30%, the regulator maintains stable output voltage within 0.25%. Fortotal harmonic distortion of the generator output voltage waveform up to40%, the regulator maintains stable output voltage within 0.50%. Thesevalues are based on a typical 6 SCR bridge.

    Reactive droop adjustment Adjustable from 0 to 10%.

    Overexcitation protection Shuts off generator output when excitation current exceeds normaloperating currents for 10 seconds or instantaneous shutoff if output currentexceeds approximately 28 Amperes.

    Ambient operating temperature 40 C (40 F) to +70 C (+ 158 F).Storage temperature range 40 C (40 F) to +85 C (+ 185 F).Power dissipation 5 watts at idle, 55 watts at rated output.
